roInt & roInteger

Really don't know what is going on with this. I have an array that I know contains certain values. I am using a control value that I know exist in the array to search for in the array. The control value types as roInteger. The array element value types as roInt. Like I said, I know the value exist in the particular field. Is it possible that I get a false on my return due to a roInt compared to roInteger? Can a roInt be converted to roInteger?
Thanks

Re: roInt & roInteger

There is no "roInteger" - there are "Integer" and "roInt", which is a boxed Integer.
Don't worry about it - they completely miscible - for comparison, arithmetics etc

Re: roInt & roInteger

Thanks. If there is no roInteger why does the debugger show roInteger?

It does?! Where?
Show a snippet from the console pls

This is from debugger window, didn't copy whole thing. The rointeger is the type of the current time as seconds rounded to nearest half hour. I actually found why my code was failing in the initial question. Thought maybe it had something to do with the types.

Re: roInt & roInteger

I too have the roInteger data type on an up to date system with software version 7.6.0 build 4125. 

I cannot cast it to a native Integer, which is causing me problems in development. Overall the language has been terrible to develop for and needs major improvements in the core language before I would use it willingly.

Above i am trying to cast the roInteger object to an integer using the % mutator.

Can you post the code that you think is giving you problems.

Re: roInt & roInteger

roInteger is just a typo for roInt in the debugger.  There should be no problem converting an object of that type to an integer.  I agree you should post your code; your problem is something different than you think it is.

Re: roInt & roInteger

I'm going to guess that cat.nid is a string (or at least not an integer).  Try printing out its type:
print type(cat.nid)

Ok, so a few things:

  1. Come on people, stop doing `CreateObject("roArray", 10, true)` and `CreateObject("roAssociativeArray")` when can say `[ ]` or `{ }`. Not only is this shorter and more readable - but it is actually faster.

  2. I am guessing the above you get an error because you are trying to index roAA with an integer. Unlike other scripting languages however, B/S takes only strings as dictionary keys - so do `m.Categories[cat.nidtoStr()] = {}` above

  3. if you want to check for a type, better to check for capability than type() equaling particular string literal, i.e. `if GetInterface(myVar, "ifInt") <> invalid then ...` - that handles both boxed and unboxed types
